Did you know…Radon is a cancer-causing natural radioactive gas that you can’t see or smell. Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe.

Did you know…Radon can be found all over the U.S. It can get into any type of building– homes, offices and schools– and can climb to high levels if it’s trapped indoors.  

Did you know…It’s the leading cause of lung cancer among nonsmokers and claims about 20,000 lives every year. Although some lung cancers can be treated, the survival rate is one of the lowest for those with cancer. Fortunately, many of the causes of lung cancer can be prevented– and this is especially true for radon.

Did you know…The Office of the Surgeon General has issued a health advisory warning Americans about the risk from breathing radon in indoor air. Americans are urged to test their homes to find out how much radon they might be breathing.

Did you know…For most Americans, the greatest exposure to radon is in their homes, whether those homes are old or new. Any home, any type, any location can have a radon problem. If your home has not been tested, now is a good time to take the test. This will help protect your family’s health and it’s easy to do.

Did you know…The U.S. Environmental Protection Agency (EPA) recommends homes be fixed if the radon level is 4 picocuries per liter of air (4pCi/L) or above. While testing can be easy and inexpensive, millions of Americans have yet to take this first important step to protect their family. 

Did you know…Hamilton, Butler and Warren counties in Ohio are all in zone 1, which means that the average of all homes tested exceed 4pCi/L.   All homes are recommended to be tested regardless of zone.  

Did you know…Testing is affordable and it’s the only way to tell…
